Aapua, Sweden wind farm facts and numbers

Aapua wind farm is located in Norrbotten County, Sweden. It was completed in 2010 and is owned by .

It is near Övertorneå.

See below for data.

Wind farms, as a general rule require wind speeds of 4.5 metres per second or higher.

The best location for something similar to Aapua would be a steady supply of non-turbulent wind. Additionally, you would not get a turbine like included if Aapua was not built near local demand or transmission capaÖvertorneå.

During the planning stages the Aapua wind farm would’ve been checked and validated through wind measurements. Meteorological wind data alone is usually not adequate for correct siting of a large wind power project.

Assortment of site-specific data for wind speed and direction would have been vital to determining site potential as a way to fund the project. Local winds are frequently watched for a year or more, and detailed wind maps created before wind generators are installed.

Altitude would also possess a part to performwithin a project like Aapua. This is due to drag The surge in velocity with altitude is most remarkable near the surface and is affected by topography, surface roughness, and upwind limitations such as trees or buildings. Velocity boosts with altitude and is more distinct near land and is altered by landscape, surface and obstructions.

Wind speeds raising with altitude is part of a wind energy law. This predicts wind speed rises with the 7th root of altitude. Doubling the altitude of a turbine, then, enhances the expected wind speeds by 10%, and the anticipated power by 34%.

In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is set between each turbine in a fully developed wind farm. However this is not always the way it is in hilly areas.

Individual turbines at Aapua are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.

At a substation, this particular medium-voltage electric current is increased in voltage with a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires setting up the collector system and substation, and possibly roads to each turbine site.
